<p>
There are two <b>types of files:</b>
<ul>
<li><b>input data files</b> (names ending with &#147;<b>dat</b>&#148;), and</li>
<li><b>output plot files</b> (names ending with &#147;<b>plt</b>&#148;).</li>
</ul>
SPANA reads an input data file, and asks you what do you want to change before
making the diagram and displaying it. <a href="DB_0_Main.htm">DATABASE</a> is used
to make input data files.</p>

<p>By default the name of the output plot file is the same as that of the
input data file. For example, if the name of the input file is
&#147;<tt>Fe2.dat</tt>&#148;, then the name of the diagram is by default
&#147;<tt>Fe2.plt</tt>&#148;. But you can, and should, choose any other name
when <a href="S_Making_Diagrams.htm">making the diagram</a>.</p>

</td></tr></table>

<p>There are several ways to <b>open a file</b> with SPANA:
<ul>
<li><u>Drag-and-drop:</u> in the Windows&rsquo; File Explorer drag the file and drop it into the
main SPANA window</li>
<li>Use the File menu of the main SPANA window</li>
<li>Associate a file extension with SPANA and
double-click on the file name in the Windows&rsquo; File Explorer</li>
</ul></p>
<p>When a file is opened it is added to one of the two file lists:
<center>
<img src="images/Spana_file_lists.gif" alt="Spana File Lists" title="Spana File Lists" height="126" width="220" border="0">
</center>
</p>

<p>Selecting a plot file from the plot-file list will display the diagram and bring
it on top of all other windows.</p>

<p>The input data file selected in the data-file list is used when selecting
the menu <nobr>&#147;Run</nobr> / Make a <nobr>Diagram&#148;.</nobr></p>

<h4>Working without the mouse</h4>
<ul type="square">
<li>The &#147;Tab&#148; and Shift-&#147;Tab&#148; keys will move the focus
  to different fields in a window (only if there are fields and/or buttons; in a diagram
  window nothing happens). &#147;Tab&#148; moves the focus in one direction
  (usually downwards) and Shift-&#147;Tab&#148; moves in the opposite direction.</li>
<li>To exit a window:
<ul type="disc">
<li>Press the space bar while the &#147;OK&#148; or &#147;Cancel&#148; buttons
  are focussed (change the focus between buttons with the Tab or
  <nobr>Shift-Tab</nobr> keys).</li>
<li>The &#147;Esc&#148; key is equivalent to a &#147;Cancel&#148; button.</li>
<li><nobr>Alt-X</nobr> and <nobr>Alt-Enter</nobr> will
  exit any window: they are equivalent to the &#147;OK&#148; button if
  there is one in the window.</li>
</ul>
</li>
<li>Captions in fields and menus have an underlined letter and they may be invoked
  by using the <nobr>Alt-letter</nobr> combination. For example select the menu
  <nobr>&#147;<u>F</u>ile&#148;</nobr> by typing <nobr>Alt-F.</nobr></li>
